t_gtkwave_diff is failing because gtkwave has updated fstapi.[ch]:

Some questions:
What is this repo we're looking at in verilator_ext_tests?
Did gtkwave move to GitHub? Google seems to think it's still on Sourceforge.

The test is mad about this gtkwave commit:
which adds Verilator helper functions. Is this anticipated?

This diff is mostly new functions, however there are other small changes. I can copy this into Verilator and check the regression tests if desired to make verilator_ext_tests happy. However, if gtkwave is really being hosted on GitHub now, should we just make gtkwave a submodule of Verilator? That way we can stop copying these files around and lose the consistency check.

I had added the ext test to catch this sort of delta.

Gtkwave is now in github, that repo is the new master.

Until we have a more serious need, I'd like to avoid submodule requirements, as it adds friction which may reduce people's ability to install it.

Anyhow, the API change was on a request I had made for a performance enhancement, so updated everything to latest and updated our calling code for the new API.

Passes locally, presuming will satisfy Travis, if not reopen.
